hello everybody. So, I had a problem last week. As I was driving home, out of nowhere, I heard a "Pop" then car stalled. Could not restart. called AAA towed it home. Next day car cranked over? I replaced ignition lock cylinder. I am also going to change-out "ignition starter switch" the one on top of the column. Also, Neutral safety switch, AKA, "reverse light switch. I found a wire under the column, a White wire to be exact. I think it is part of the "directional/cruise" harness. I have looked high and low for wiring diagrams for "steering wheel/directional" drawings. I have GM books, however. I have found NOTHING! Does anybody have a wiring schematic for steering column and ALL related switches involved? It's driving me nuts...
